Whakaoti i te (3/2*4)(1/6:1/2)9/10

$$( \frac { 3 } { 2 } \cdot 4 ) ( \frac { 1 } { 6 } : \frac { 1 } { 2 } ) \frac { 9 } { 10 }$$

Aromātai

$$\frac{9}{5}=1.8$$

Ngā Upane Otinga

Tuhia te \frac{3}{2}\times 4 hei hautanga kotahi.

$$\frac{3\times 4}{2}\times \frac{\frac{1}{6}}{\frac{1}{2}}\times \frac{9}{10}$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{12}{2}\times \frac{\frac{1}{6}}{\frac{1}{2}}\times \frac{9}{10}$$

Whakawehea te 12 ki te 2, kia riro ko 6.

$$6\times \frac{\frac{1}{6}}{\frac{1}{2}}\times \frac{9}{10}$$

Whakawehe \frac{1}{6} ki te \frac{1}{2} mā te whakarea \frac{1}{6} ki te tau huripoki o \frac{1}{2}.

$$6\times \frac{1}{6}\times 2\times \frac{9}{10}$$

Whakareatia te \frac{1}{6} ki te 2, ka \frac{2}{6}.

$$6\times \frac{2}{6}\times \frac{9}{10}$$

Whakahekea te hautanga \frac{2}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$6\times \frac{1}{3}\times \frac{9}{10}$$

Whakareatia te 6 ki te \frac{1}{3}, ka \frac{6}{3}.

$$\frac{6}{3}\times \frac{9}{10}$$

Whakawehea te 6 ki te 3, kia riro ko 2.

$$2\times \frac{9}{10}$$

Tuhia te 2\times \frac{9}{10} hei hautanga kotahi.

$$\frac{2\times 9}{10}$$

Whakareatia te 2 ki te 9, ka 18.

$$\frac{18}{10}$$

Whakahekea te hautanga \frac{18}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{9}{5}$$

Tauwehe

$$\frac{3 ^ {2}}{5} = 1\frac{4}{5} = 1.8$$
